使用说明 (SKILL.md)
HealthProbe
Check if a URL is up before you call it.
Start the server
uvicorn healthprobe.app:app --port 8009
Probe a URL
curl -s -X POST http://localhost:8009/v1/probe \
-H "Content-Type: application/json" \
-d '{"url": "https://example.com"}' | jq
Returns healthy (true if 2xx), status_code (HTTP code or -1 on error), latency_ms, and error (if connection failed).
With custom timeout
curl -s -X POST http://localhost:8009/v1/probe \
-H "Content-Type: application/json" \
-d '{"url": "https://slow-api.example.com", "timeout_ms": 1000}' | jq '.healthy'
Timeout range: 100ms to 30,000ms (default: 5,000ms).
安全使用建议
This skill appears to do exactly what it says: run a local HTTP service that probes arbitrary URLs. Before installing, consider: (1) SSRF risk — the skill will perform outbound requests to any URL you pass it, including internal IPs or cloud metadata endpoints; run it in an isolated environment or restrict egress if you don't want internal scanning. (2) Supply-chain caution — pip packages are not version-pinned; consider pinning or auditing dependencies before installation. (3) Operational limits — the server listens on a port (example uses 8009); ensure it is firewall-protected if you run it on a shared host. If you plan to allow autonomous agent use of this skill, restrict or validate target URLs to avoid unintended network probing.
功能分析
Type: OpenClaw Skill
Name: healthprobe
Version: 1.0.0
The skill provides a FastAPI-based service to probe arbitrary URLs, which introduces a Server-Side Request Forgery (SSRF) risk as it lacks restrictions on internal IP ranges or local endpoints. While this network access is plausibly needed for the stated purpose in SKILL.md, the implementation in healthprobe/app.py and healthprobe/models.py allows an agent to interact with potentially sensitive internal infrastructure. No evidence of intentional malice, data exfiltration, or obfuscation was found.
能力评估
Purpose & Capability
Name/description, declared binaries (python), declared dependencies (fastapi, uvicorn, pydantic, httpx), and code implementing /v1/probe all align with a URL health-checking service.
Instruction Scope
SKILL.md instructs running a local FastAPI server and POSTing arbitrary URLs to /v1/probe — this is consistent with purpose. However, the ability to request any URL means the skill can be used to reach internal services (SSRF/internal network scanning) or cloud metadata endpoints if not sandboxed; the README does not include any allowlist/denylist or additional safeguards.
Install Mechanism
Install spec uses PyPI packages (fastapi, uvicorn, pydantic, httpx), which is expected. Risk: packages are not version-pinned in the manifest, creating a supply-chain risk if you want to lock reproducible installs.
Credentials
The skill requires no environment variables, no credentials, and no config paths — this is proportionate to a network probe service.
Persistence & Privilege
The skill is not forced-always, does not request elevated persistence, and does not modify other skills or system-wide configs. It runs a local server when started, which is expected for this design.
